Hello and thank you for using JustAnswer.com

this noise or vibration.

Does it sound like the rumble strips on the side of the highway?

Let me know, Thanks Jay!

What is your exact mileage?

This is important to know...

This could be the trans making this noise.

There is a known issue on this

You are going to need to have this checked asap, and I will explain

\The 2005 through 2010 Nissan Pathfinder, Xttera and Frontier got a warranty extension on there Radiators. This extension is for 8 years or 80k miles. The reason for this extension is cause the trans cooler inside the radiators have been failing prematurely. When this happens coolant can enter the trans, and trans fluid can enter the coolant system. But when coolant enters the trans, it contaminates it. Once this problem start, you may feel a vibration at highway speeds. This vibration may resemble the rumble strips on the side of the highway. If you have this type of vibration, then your trans has been contaminated by the coolant. If your with in the 8 years or 80k miles Nissan will cover the transmission if it was damaged by the radiator, because the radiator is the cause of the condition or failure. So the radiator and trans would be replaced under warranty

But your under 80k miles so if the trans is contaminated by the radiator failure, the trans would be replaced under warranty with the radiator.

But your going to want to have this checked asap, since your close to the end of the warranty extention

It can make the trans fluid a pink color

but before it actually does, it may not affect fluid visually.

But this is some thing that I would go to the local dealer to have checked asap

If the dealer doesn't find any problems like this, then at least you have it noted in the system

So if this problem does get worse and does turn out to be the trans cooler issue and your out of warranty, they should honor the repair

If you have any more questions on this, please feel free to ask. Thanks Jay!
